The Future Of Aviation? Why Rolls-Royce Filed A Patent For A Hydrogen Engine System
Rolls-Royce has patented a new hydrogen fuel system for gas turbine engines that addresses a major challenge in hydrogen aviation: the extreme cold temperature of liquid hydrogen. The system uses an auxiliary combustor to pre-heat hydrogen fuel before it reaches the main engine, creating a more stable and controlled combustion process.
